What are the temperature at the lower and upper level of stratosphere?

Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

Why is the temperature of the stratosphere higher than the troposphere?

The infamous ozone layer is found within the stratosphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. Unlike the troposphere, the stratosphere actually gets warmer the higher you go!

Why does the temperature increase in the stratosphere and decrease in the mesosphere?

Temperature decreases with height throughout the mesosphere. The air is much thinner (less dense) in the mesosphere than in the stratosphere below. There are fewer air molecules, including ozone molecules which play such an important role in heating the stratosphere, to absorb incoming solar electromagnetic radiation.

What is the temperature of the lower stratosphere?

Extremely low temperatures are a general characteristic of the lower stratosphere, with a range from –40° to –80°C. A dominant feature in the chemical characteristics of the lower stratosphere is the presence of ozone.

What is the highest temperature in the stratosphere?

Within the stratosphere temperatures increase with altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (−3°C or 26.6°F).

Which layer of atmosphere has highest temperature?

The thermosphere
The thermosphere is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 ºC in this layer (Wallace and Hobbs 24).

How does temperature change as you go higher and higher in the stratosphere?

The temperature increases with increasing altitude in the stratosphere because there’s a high concentration of ozone molecules. These ozone molecules absorb UV rays from the Sun and then radiates this energy in the form of infrared waves. Nearby gases can absorb this infrared energy and increase in temperature.

Is the air pressure in the stratosphere high or low?

This region of increasing temperatures is the stratosphere, spanning a pressure range from 100 millibars at its base to about 10 millibars at the stratopause, the top of the layer.

At what height in the troposphere does the temperature decrease?

The troposphere is the layer next to Earth’s surface. On the average, it extends 11 km to the top of the troposphere which is called the tropopause. In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere’s gases absorb very little of the incoming solar radiation.

Which layer of the atmosphere has the lowest temperature?

| Report | Fact Sheet | Test | Answers | FAQ |. Report. The troposphere is the lowest layer of Earth’s atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.

How high above the ground is the troposphere?

Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. We humans live in the troposphere, and nearly all weather occurs in this lowest layer.

What is the temperature at the top of the stratosphere?

Stratosphere. In this region the temperature increases with height. Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere.

Why don’t planes fly in the stratosphere?

That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Commercial passenger jets mostly fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride.
